[0115] After the implementation of the present invention is successful, the user's usage process is as follows:

[0116] S301: Complete the installation of hardware such as the projection module, fusion device, main control computer, and projection display screen. Place the projection standard module board on the display screen, turn on the power, and the projection module calibration control software will start automatically. The display interface is as Figure 2 shown;

[0117] S302: Click the projection module selection button in "Select Module" on the main interface to select a projection module. The serial number of the projection module will be displayed in the corresponding dialog box of this projection module, as Figure 2 shown. The first projection module is selected by the user, and its serial number is 12011209.

[0118] S303: Click the "Load Parameters" button, and the projection module calibration control software;

[0119] reads the parameters of this projection module from the local main control computer for automatic calibration control. If not found locally, it reads the parameters from the projection module for automatic calibration control. If the projection module does not store parameters or the parameters do not meet the requirements, adjust according to the following steps;

[0120] Select an anchor point of the projection module through the "W", "S", "A", "D" keys on the keyboard, such as Figure 2 the orange anchor point in the figure, and adjust the position of the anchor point through the "↑", "↓", "←", "→" keys on the keyboard to align the anchor point with the line on the standard module board.

[0121] S304: Repeat step S303 until all the anchor points corresponding to this projection module are adjusted to align with the lines on the standard module board;

[0122] S305: Adjust the focal length of this projection module by using the two buttons of "Forward Focus Adjustment" and "Reverse Focus Adjustment" in "Focal Length Adjustment" until the focus is the clearest;

[0123] S306: Set the brightness of this projection module to "80" in the "Brightness Setting" file box, and click the "Set" button to complete the brightness setting;

[0125] S308: Click "Save Parameters to Local" to save the adjusted projection parameters to the local main control computer; click "Save Parameters to Module" to save the adjusted projection parameters to this projection module. At the same time, the parameters will be loaded into the fuser, thus completing the adjustment of the parameters of this module.

[0126] The present invention designs the whole process of projection module calibration control. By using the calibration control method designed by the present invention, the fuser can realize the splicing fusion, precision adjustment and brightness control of any number of projection modules. Especially in the case of replacing one or more projection modules, the fuser parameters can be automatically updated, and the overall projection calibration control of the device can be quickly realized, saving the cost of returning to the factory for repair. The present invention can be used in paper chart navigation equipment such as nautical workbenches and nautical chart plotting tables, and other large equipment with projection requirements and requiring the fusion of multiple projection modules. Without professional guidance, anyone can realize the fusion splicing of multiple projection modules by using the calibration control method of the present invention.

[0127] As Figure 5 shown, determine whether a user instruction is received. If no user instruction is received, return for re-determination. If a user instruction is received, determine whether the received instruction selects a projection module. If a projection module is not selected, re-determine the received instruction. If a projection module is selected, determine the projection module number, that is, the projection module serial number (1 - xx), and initialize the device address information of the selected projection module. The device address information includes the IP address and ID; turn off the network debugging of the fuser, turn on the network debugging of the fuser, set the fuser control instructions (including instruction type, card type, background color, etc.), and send them to the specified module through the network. Send a read serial number instruction to the selected projector module through the serial port, obtain the module feedback message through the serial port and parse to obtain the serial number of this module, and display this projection module serial number on the corresponding interface. Determine whether the display of the selected module serial number is normal. If it is not normal, re-determine the received instruction. If it is normal, determine the operation of the user on the selected projection module.

[0128] Determine whether an anchor point is selected, determine the moving direction of the anchor point, and adjust the position of the anchor point by using the up, down, left, and right keys to align the anchor point with the line on the standard module board to complete the anchor point calibration.

[0129] Determine whether to adjust the focal length, determine the adjustment direction, and use the forward and backward keys to adjust the focal length of the projection module to make the projection module focus most clearly, thus completing the focal length adjustment.

[0130] Determine whether to adjust the brightness, obtain the user's brightness setting value, and send it to the corresponding projection module through the serial port to complete the brightness adjustment.

[0131] Obtain the serial number of the corresponding module, display it on the interface of the corresponding module, and determine whether the serial number is normal. If it is not normal, re-obtain the serial number of the corresponding module. If it is normal, generate a file named after the serial number, and determine whether there is a file with this file name locally. If it exists, load it into the fuser to complete the parameter loading; if it does not exist, read the post-parameter file from the serial port, and determine whether the read file is normal. If it is not normal, re-read the post-parameter file from the serial port. If it is normal, decompress the file and load it into the fuser to complete the parameter loading.

[0132] Obtain the serial number of the corresponding module and generate a file named after the serial number. Determine whether the file naming is normal. If it is not normal, save it locally. If it is normal, generate a file named after the serial number, and determine whether the file is empty. If it is empty, save it locally. If it is not empty, save the fuser configuration parameters and then save them locally.

[0133] Obtain the serial number of the corresponding module and generate a file named after it. The judgment process is the same as saving to local. Determine whether there is a file to be saved locally. If it exists, compress it into 7z format, send it through the serial port, and display it on the feedback interface to complete saving to the corresponding projection module. If it does not exist, first save it locally, then compress it into 7z format, send it through the serial port, and display it on the feedback interface to complete saving to the corresponding projection module.
